The film also features Prateik Babbar, Ashutosh Rana and Neena Gupta.

While Rajat was to initially essay Rishi Kapoor’s younger brother in the film, Manoj was to play a tough police officer.

Sinha said in a statement: “I always wanted Manoj Pahwa and Rajat Kapoor in the primary cast for ‘Mulk’. While I had envisaged a different role for both of them in the film, it was only when they came in together on sets after the recce did I realise that they were both meant to play different roles.

“They were both pretty quick in adapting to a new role.”

The teaser of the film shows Rishi Kapoor playing a character called Murad Ali Mohammed, accused of treason. Actress Taapsee Pannu plays his defence lawyer Aarti Mohammed.

The film is based on a series of true events, and is slated to hit the screens on August 3.

“Though we have worked in just two films, a lovely co actor and poker player, Rajat Kapoor. The only irritant about him is he is a teetotaller, unlike me, and doesn’t carry a mobile. An under-used actor waiting to burst. Go man go,” Rishi tweeted on Saturday.

Presented by Kamal Mukut and Soham Rockstar Entertainment, a Benaras Media Works production, the film is produced by Sinha and Deepak Mukut. The film also features Prateik Babbar, Ashutosh Rana and Neena Gupta.
